A reader wrote to point out that the celebrated philosopher, Saul Kripke (68 years old this year), never completed an academic degree beyond his B.A. at Harvard. Gives one pause about the value of those six-to-ten years of self-promotional shenanigans generally required to garner oneself a professional job. See "The celebrated Saul Kripke never earned more than a B.A." (Philosophia Perennis, April 28, 2008).
